You begin as an asteroid. Absorb everything smaller than you, stay clear of everything larger, and keep growing through planets, stars, black holes and galaxies until the universe itself gives way.
Touching a larger body drains your mass into it. Touching a smaller one feeds you. Bodies drift, pull on each other and eat each other too. Planets can capture small moons, and a planet that devours something far smaller grows a ring.
